Abstract
A plurality of signal lines receiving signals with different phases are connected to the reference potential point through switching elements. The switching elements connected to signal lines other than the signal line receiving an active signal are rendered conductive by the active signal on the signal line and the other signal lines are led to the reference potential.

A wave shaping circuit comprising:
- a plurality of signal lines connected to receive a plurality of clock signals having different phases and apply the clock signals to a capacitive active device, each of said clock signals having an active level to activate the capacitive active device and a non-active level;
- a plurality of switching circuits connected between a reference potential point and said signal lines, each of said switching circuits having a control signal input means connected to at least one of said signal lines adjacent to that one of the signal lines to which said each of said switching circuits is connected, wherein a switching circuit connected through the control signal input means to a signal line receiving an active level clock signal is rendered conductive and drives said adjacent signal line to the reference potential point.
A wave shaping circuit comprising:
- a plurality of signal lines connected to receive a plurality of clock signals having different phases and apply the clock signals to a capacitive active device, each of said clock signals having non-overlapping active levels to activate the capacitive active device and a non-active level;
- a plurality of switching circuits connected between a reference potential point and said signal lines, each of said switching circuits having a control signal input means connected to the signal lines adjacent to that one of the signal lines to which said each of said switching circuits is connected, wherein the switching circuits connected through the control signal input means to one of said signal lines supplied with an active level of said clock signal are rendered conductive and drive the signal lines not receiving an active level clock signal to the reference point.
A wave shaping circuit comprising:
- a plurality of signal lines connected to receive a plurality of clock signals having different phases and apply the signals to a capacitive active device;
- each of said clock signals having non-overlapping active levels to activate the capacitive active device and a non-active level;
- and a plurality of switching circuits connected between a reference potential point and said signal lines and having control signal input means to receive switching control signals;
- wherein each of said signal lines is connected to said control signal input means of said switching circuits corresponding to other signal lines, and when said clock signal with active level is transmitted to at least one of said signal lines, the active level of the clock signal is applied to the control signal input means of said switching circuits corresponding to said other signal lines to render said switching circuit conductive and drive said remaining signal lines to the reference potential.
